Hello, I tested the code you posted in the HelloUniverse and it never caused deadlock. I also modified the code to create a new frame and show it with the canvas. This also worked.
Linux/J2SDK 1.4.2_04/OGL/Java3D 1.3.2b4 There should not be a problem with swing deadlocking since the action listener will be called from the swing thread. -mike -----Original Message----- From: Discussion list for Java 3D API [mailto:[EMAIL PROTECTED] On Behalf Of N. Vaidya Sent: Thursday, July 08, 2004 8:48 AM To: [EMAIL PROTECTED] Subject: [JAVA3D] Issue with Runtime instantiation of Canvas3D Hmm...This is really weird. All I'm trying to do is to instantiate a Canvas3D in Swing's EDT - simply instantiate and not even add it to the View - and I find that causes the app. to freeze. The testcase is HelloWorld.java in the Java3D demo bundle with the inclusion of the following code snippet in the init method (the snippet to be included is the block between the BeginMods and EndMods comments; a few lines below and after the block are duplicated to indicate where the snippet should be pasted in the init() method). Upon launching the app., you'll find a rotating cube and a JButton named "Create Canvas3D". Upon pressing that button, which actually results in the instantiation of a new Canvas3D, on my config. I find that the cube stops rotating. Also try resizing the canvas to see what happens. Is there anything odd with the GraphicsConfiguration returned by SimpleUniverse ? I'm using Java3D 1.3.2-build3 and j2sdk1.4.2_03 on P4 WinXPs. =========================================================== public void init() { setLayout(new BorderLayout()); GraphicsConfiguration config = SimpleUniverse.getPreferredConfiguration(); Canvas3D c = new Canvas3D(config); add("Center", c); // BeginMods =======> javax.swing.JButton canBtn = new javax.swing.JButton("Create Canvas3D"); canBtn.addActionListener( new ActionListener() { public void actionPerformed( ActionEvent e ) { Canvas3D newC = new Canvas3D(SimpleUniverse.getPreferredConfiguration()); } }); add("South", canBtn); // EndMods ========> // Create a simple scene and attach it to the virtual universe BranchGroup scene = createSceneGraph(); ========================================================= TIA --Vaidya =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
